ok, i changed every occurence and i can do a modified handshake with telnet. but it won't connect if i use the modified programs.
i think it is not a problem with the handshake, i think it is because limewire wants to connect to ultra peers and refuses in the beginning to connect to leaf nodes. is this right?
is there the possibility to change this behavior or to force one of my (two) clients to be a ultra peer?

thanks
